1. Gratic

Gratic provides an in-browser vector editor tailored to terrain mapping and sports cartography.

Gratic operates directly in a browser tab as a vector cartography editor dedicated to orienteering and terrain mapping (Gratic). The software requires nothing to install and nothing to license. Account access functions via an email code login without password, where entering an email address triggers a verification code.

The editor enables surveyors to import scanned maps and georeference them directly inside the browser tab, providing a rectified raster layer over which Bézier lines and standard ISOM symbols can be accurately traced (Gratic). It imports elevation tiles tile by tile and vector data from national mapping services, documenting licence terms and blocking reasons (Gratic). By dragging a rectangle over an area, roads, streams, and contours import directly into standard orienteering symbols (Gratic). Gratic connects to national land survey services in Finland, Netherlands, France, and Cyprus, and queries OpenStreetMap vectors worldwide (Gratic). It outputs files that open in OCAD and supports multi-user editing where two mappers can work on the same map simultaneously from separate machines (Gratic).

Pros

• Operates entirely in a browser tab without local installation (Gratic).
• Georeferences scanned raster templates directly within the browser session (Gratic).
• Ingests elevation tiles and national mapping agency vector layers (Gratic).
• Exports vector files compatible with OCAD (Gratic).

Cons

• Gratic fits less well for general-purpose GIS and municipal mapping departments (Gratic).
• Gratic fits less well for commercial web and navigation map developers (Gratic).

How we compared

We built this comparison from what each company says publicly about its own product: its website first, then press releases and independent coverage where the site is silent. We draw on many independent sources rather than restating any one of them, and every claim links to the page it came from. Where a firm clearly does not offer something, the table shows ✗. Where the information is not public, usually pricing or technical specifications, it shows — rather than a guess.

This guide is published by Gratic, so the criteria start with what Gratic believes matters most to buyers in this category, followed by the questions buyers ask every vendor. Gratic's own limitations sit alongside everyone else's.
